T0 a.ZZ whom zt may concern:

Be it known that I, CRAIG S. LOSIE, of the city of Hornellsville,in the oounty of Stenben, and in the State of New York, have invented certain new and useful Improvements in Flooring-Jacks and I do hereby declare that the folloWing is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

The object of my invention is to provide an improved means for drawing or wedging np any tongue-and-grooved material of va.- rious thicknesscs in whatever way, shape, or manner the same may be applied to build- 1ngs.

My improvement consists, essentially, in a lever that has an adjustable pin attached to it, which acts as a fulcrum to the lever, which turns in a slot eut in a head, which is enlarged at its top to form a place to strike and drive pin in. The head is an extension of a sleeve that travels on the lever, and it is moved to and held in any desired position by a thumb-screw placed in a notch and upon a pin that is secured in an npset on the lever and an arm With two sets of jaws attached to it, (one set at each end.) Upper jaws are adjustable and are raised and secured With a thumb-screw, so as to coincide With thickncss of tongue of the board to which the jack is applied. The lower jaws are an extension of and part of arm and are toothed. These teeth enter the wood under the tongue of board and prevent the same from slipping ont. J aws have rubber cushions that conform to their shape and are secured to the upper jaws.

In the accompaning drawings, Figure 1 is a plan view of adjustable flooringjack containing my invention. Fig. 2 is a plan view of arm. Fig. 3 is a vertical horizontaisection of Fig. 1 in line oc. Fig. 4: is a side view of pin.

A is the metal lever.

A is a notch out in A.

uis an upset t0 strengthen A and to receive p, upon which the thumb-screw S turns.

B is a metal arm, s0 construeted as to allow the lever to describe an arc et a circle and is secured to A With rivets 11 and screw 17', Fig. 3.

C represents metal jaws, of which there are two sets, one set at each end of B.

0 is a partial view of loWer jaw, which is an extension of B and is toothed at 0, Figs. 2 and 3.

0 is a rubber cushion and conforms to shape of jaws and is seeured t0 upper jaws with screws 3, Fig. 2. These upper jaws travel on guides. Back guide is square in form and is part of lug 0', Fig. 2.

0' is front guide and is secured to upper jaw and passes through hole in 111g 0', Fig. 2, when jaws are raised, which is done with thumb-screws S, Figs. 1, 2, and 3.

D is metallic sleeve that travels on A and fits in notch A and is moved to and held in any desired position by thumb-screw S, Fig. 3, which passes throngh its center, and it has head H formed upon it, which has face d raised upon it and slot j ont out to receive pin E, Fig. 3.

E is a metal pin which acts as a fulcrum to the lever and turns in slot j of head H, Fig. 3, and has bearing at its upper end and shoul ders 6 at E, Fig. 4, and also has a bearing on the circumference of head II at e, Fig. 3, thereby relieving pin 6, Fig. 3, of all unnecessary strain.

It will be seen that by placing the jack in a perpendicular position and raising the jaws 0 With thumbscrew S t0 coincide With the tongue of board and driving on face (1, Which forces in pin E, Fig. 3, to secure a purchase,

and then pushing on the lever it will draw board up tight and.hold it there until it is secured, when the jack can be released; also, that the rubber cushions 0, Fig. 3, will prevent all marring and jamming of the boards.

This invention can be used on boards that are not matched, as the teeth 0, Fig. 2, will penetrate the board far enongh to hold it while it is being drawn up.

What I claim as my invention is- An adjustable flooringjack comprising a lever, a screw in said lever, a head mounted on and adjustable by said screw, a pin carried by said head, jaws adjustable to the size of theboards to be operated upon, one set of jaws having rubber cushions and one set being serrated, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 17th day of February, 1899.

CRAIG S. LOSIE.
